Application September 7, 1937, Serial No. 162,824 2 Claims. (Cl. 254-135) My invention relates to blocks commonly used in the tackle of logging lines, ships’ lines and in 8 upon the outer head engaging end of the ball any and all places where relatively heavy loads t so that the anti-friction bearings, as roller are to be handled‘and swung and suspended from bearings, roll within the ball and upon the roller overhead lines or from crane booms and the like. My invention is comprised primarily of a body element having a plurality of ball and socket swiveling heads swiveling about their longitudinal central axes and for moving the ball and socket it joint within the body element. The primary purpose and object of my inven tion is to provide a plurality of supports, all rotat ably disposed within a common body element to provide a common support for a plurality of handling lines that are to be secured thereto. A still further object of my invention consists‘ in providing an overhead support that may be suspended from a line boom or other support and to which is attached a plurality of lines, each 20 head may have an independent line attached and secured thereto. Each swiveling head has an eye formed in the outer end to facilitate the at taching of a fastening line thereto. With these and incidental objects in View, the invention consists in certain novel features of construction and combination of parts, the es sential elements of which are set forth in the appended claims, and a preferred form of em bodiment of which is hereinafter shown with 30 reference to the drawing which accompanies and forms a part of this speci?cation. In the drawing: race of the ball and the underside of the head. A neck iii of the eye support runs through the ball and connects the eye “3A with the head. A rim is disposed between the side walls, as illus trated at H and I2. ‘ In the manufacture of the device the rim is preferably formed integral with one of the side Walls and after the assembly is completed the other one of the side walls is then secured there to by suitable fastening means as through the use of bolts or the same may be welded thereto. I recess the rim, as illustrated at I4 to permit 15 a swinging action of the assembly within the socket. A collar I3 is disposed between the eye and the head. The side walls of the body element are preferably made triangular in form with each of the corners being rounded, as illus 20 trated at 15 and I6. This provides a supporting tackle member having a plurality of line sup ports which may be secured thereto. The swiveling heads may be of uniform size or where one of them is to be used as the primary 25 support and the other supports may be made smaller as it is apparent that the total load would be supported by one of the swiveling heads and each of the others would individually support a lesser amount of load when all of the heads 30 are supporting loaded lines. While the form of mechanism herein shown Fig. l is a plan view of a three-way swivel. Fig. 2 is a side View of the device illustrated in 35 Fig. 1. Fig. 3 is a fragmentary, partially sectional, plan view of the three-way swivel. Like reference characters refer to like parts throughout the several views. forms, all coming within the scope of the claims 40 which follow. I form my device of a body element I. The body element l is recessed upon its inner side and is primarily comprised of spaced front and back walls secured together on their peripheral edges by being secured to a rim. swiveling heads, here shown as three in number are illustrated at 2, 3, and it. A socket 5 is provided for each of the swiveling heads and a section of a spherical ball ii is provided for coacting with and being moved within the socket 5. A head ‘i is disposed upon the inner end of the eye support and the head I may rest directly upon the ball 6 or I may provide anti-friction bearings between the head I and the ball 6. In order to provide a suitable raceway for the anti-friction bearings, here shown as roller bearings, I provide a rim and described is admirably adapted to ful?ll the objects primarily stated, it is to be understood that it is not intended to con?ne the invention to the embodiment herein shown and described, as it is susceptible of embodiment in various ‘ What I claim is: v40 1. In a device of the class described, the com bination of a body element that is comprised of spaced side walls that are secured together at their peripheral edges by a rim, socket joints dis posed within the rim at spaced intervals, a sec 45 tion of a spherical ball ?tted to each of the sockets, an anti-friction bearing race disposed at one side of the ball section, anti-friction bear ings positioned within the bearing race, an eye fastening passing through the section or" the ball, and headed over to complete the anti-friction bearing race for the anti-friction bearings and a spaced slit disposed in the rim of the assembly through which the neck of the eye member may be made to oscillate. 65 2 2,139,294 2. In a device of the class described, the com bination of a body element that is comprised of a, rim and spaced side walls that are secured to‘ the rim, a plurality of socket bearings disposed 5 in the body element and a ball bearing disposed in each of the socket bearings, an eye swiveling head coacting with each of the ball and socket assemblies associated with the body element and a. slit in the rim of the body element through which the swiveling head is permitted to oscillate. 5 ANTHONY WEIGANT.
